Christy Wilhelmi's At Home Drip Irrigation

Installing drip irrigation is kind of like building LEGOs. There are many different hoses and attachments to customize your set-up. Here is the simple process we used.

What you need:

  • 1 battery operated hose timer
  • Batteries
  • 1 micro sprinkler kit
    • You can buy these at hardware stores such as Home Depot
    • Our kit included
      • ¾ in. back-flow device, 25 psi ¾ in. pre-set pressure regulator, ¾ in. swivel adapter, 200 ft. ½ in. drip irrigation hose and 50 ft. ¼ in. micro tubing, 11 completely-assembled micro sprayers with 360-, 180- and 90-degree spray patterns, 13 in. stakes, 24 in. of micro tubing and twenty 1 gph pressure-compensating drip emitters. Installing in 3 steps.

Installing in 3 steps:

  1. Connect:
    • connect your timer to an outdoor spigot or hose
  2. Distribute
    • lay out tubing network through your garden
    • use ½ to ¾ inch tubing to connect to water source
    • use ¼ inch micro tubing for branch lines
    • use elbow fittings to make corners
    • tie down stakes to anchor tubing
  3. Water
    • attach emitters to ends of plant lines
    • tons of different emitters
      • pressure compensating
      • adjustable
      • foggers
      • bubblers
      • tubing with pre-installed emitters

Cover the hosing with dirt or mulch and you're done!
